Hooded hordes swarming
Over endless plains,
Recalling the hordes of people, damned as Eliot sees them, walking over the bridge. And perhaps also suggestive of people swarming over the ruins of villages and towns which were laid waste by the first world war.
Also suggestive of the (red riding hooded) Russian revolutionaries intent on abolishing empires and traditional social structures.
“Ringed by the flat horizon only” = classless or non-hierarchical society repugnant to conservative Eliot?
Even the “red rock” from “The Burial of the Dead” could be interpreted as the Socialist Church, but this might be a stretch…
